Came here to ask the same thing. Why do I _care_ if connections to my server come from a TCP proxy? Particularly when a VPN is _not_ observable in a similar way?
Is there some class of bad actors who extensively use TCP proxies and not only _don't_ use VPNs, but would incur large costs in switching to them?
